Burris Speedbead + Fast Fire II on my Benelli SNT

[PCFIVEZ]

I recently installed a Burris Speedbead + Fastfire II Optic on my Benelli Supernova Tactical. After installation, I noticed that it doesn't sit perfectly flush on the pistol grip. I can feel a very small gap on the left side as the right side sits fine. Is this a problem that should be addressed or am I just being super anal?

 

I also removed the small boomerang shaped foam sticker from the rear area to fit it on easier...does that foam serve a purpose such as shock absorbancy or alignment?

 

I co-witness the Burris along with my ghost ring sights and after a few adjustments everything lines up.
